Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557190, here are decompositions:

47 + 33557143 = 33557190
59 + 33557131 = 33557190
71 + 33557119 = 33557190
89 + 33557101 = 33557190
103 + 33557087 = 33557190
113 + 33557077 = 33557190
127 + 33557063 = 33557190
179 + 33557011 = 33557190

Showing the first eight; more decompositions exist.
